it can move in a 125 gallon.. and commons take at least 10 years to grow up to 24".. there's no point in upgrading to a huge tank in the beginning just to accommodate one fish.... besides.. that takes the fun out of upgrading tanks...
No.. i say a 125 tank is enough. and plecos only move at night.. where they do most of their feeding..
What you need to look into is medium size plecos.. I recommend snowball, gold nugget, green and blue phantom, candy stripe, flash are all good choices for plecos.. There are other species out there but you'll have to get a bigger tank.. if you only plan on doing a 55 gallon for now..
